I don't have a 2200G to test but the above is using a 3400G and I'm also using Unraid 6.9.0-rc2. This thread is dedicated to the now deprecated beta35 release and you ought to upgrade. Loading the module is trivially simple but the real question is how do you hope to use it?
Thank you for the reply @John_M
Yeah I did upgrade to RC2, and guess I should have posted this on that thread. Sorry.
My plan was to see if I can get a PLEX docker to use the APU for transcoding. I run PLEX on another system, and would love to bring it back onto unraid vs another box running. Now that I see that it is running I'm going to see if I can test it.
-
Anyone get either AMD driver to work on a 2200G or know of a way to test it or confirm that the driver is actually loaded for the APU? Been working on this for a few days off and on but so far no success.

Yeah Ryzen 3900x I did find ways on the forum which got VNC working but couldn’t get anything on the TV it was a nightmare to say the least I tried loads of different things but I’m glad it’s sorted now I tried changing passthrough to model I tried different lines I found on here and they got VNC to work but that was it 👍🏻
Same CPU as me. It's a beast for the momey.
I had a devil of a time getting my Nvidia 1070 to passthrough until I used a second video card in the system to dump the BIOS from my card. I downloaded about a dozen BIOSes from the web, but could never make them work. After I used my own BIOS I was able to pull out the other card and run with just the one video card passed through to my VM.

sorry had 10 minutes to go to work, did not have time to read both pages....
Easy to miss. For now stick to beta 25, looks like they have asked to see if the driver can be updated.

Yeah i used space invader ones video to setup awhile back I’d been using it to game on for probably 5 months before I got the probs but I just updated to beta 29 and VM is back and running well atm so Call of duty Cold War here I come thanks for the new update unraid team pls don’t do that to me again...
Ah, where you using and AMD CPU by any chance? beta 25 did have a bug that had to be worked around to allow any vm with passed through CPUs to work. but it only affected AMD 3XXX CPUs.

I tried the update this morning from beta 25 to 29
All 11 of my disks were gone upon reboot onto 29.
Rebooted again, still, everything was gone. And i mean everything!Rolled back to 25, back to normal.
What can i provide to help?
What storaage card are you using? See above below:
KNOWN ISSUE: with this release we have moved to the latest Linux 5.8 stable kernel. However, we have discovered that a regression has been introduced in the mtp3sas driver used by many LSI chipsets, e.g., LSI 9201-16e. Typically looks like this on System Devices page:
Serial Attached SCSI controller: Broadcom / LSI SAS2116 PCI-Express Fusion-MPT SAS-2 [Meteor] (rev 02)

Hey chess the work around worked for vnc for me but it wouldn’t pass through to the tv yet 6.8.3 I could passthrough to tv fine since going to beta I lost the ability I tried many fixes on here and it didn’t happen best I had was VNC and I can’t get that anymore
Hello @Dava2k7 are we talking about passing through a video card to a VM and then attaching the vm to a TV for video output or something else? Sorry a little confused, but passing through a video card to turn a vm into a virtual gaming system is possible, I'm trying on mine right now, but it can be a finicky process. If this is it and you have a thread that you started maybe I can help.

wondering if this release fix qemu 5 issue and ryzen "host-passthrough bug"
It did for me. It was the first thing I tested

Does this mean the vm’s will work again?? Thank you for all your work Unraid team
Not sure what you are asking here, but VMs always worked, but there was an issue on AMD cpus with the last beta however there was a workaround to get them to work.
-
Running beta 29 as of about an hour ago, so wanted to follow up for anyone still reading this thread. The new beta no longer needs the edits to the XML file to allow proper cpu passthrough to work and with the vm mostly idle I'm seeing about 13% usage in the VM and very similar CPU usage on the unRaid dashboard.
Also, the unRaid dashboard must be pretty CPU intensive. CPU usage jumps to about 18% on the VM with it open in Chrome

Only thing I see is HT thread 12 is being loaded up to 100%, but I doubt that has anything to do with the beta.
Odd, but this was a pinned core, with nothing using it
Unpinned it and rebooted, now it's ~15% usage with jumps up to 40ish. Kind of odd for a pinned core to have that much usage on it with nothing assigned to it, but it's all good now.
Good job on this version @limetech

Just upgraded my AMD 9300X system, and can now use Host passthrough for the CPUs again without having to make changes to the XML.
noVNC error here on any of my VMs.

So is this problem going to be ignored? It's not listed in "known issues" or something like that.
I tested the same hardware with Proxmox and I NEVER got random activity on cpus I had isolated to certain vms.
My guess is no, as isolcpus is deprecated, and while it does affect users, my guess is the affected user base is pretty small.

Could you share, what oyu have done?
Sure. I'm still getting activity on the isolated CPUs when doing a parity check or rebuild, but I can now game on the VM while this is going on without any noticeable hiccups. Right now I'm playing F1 2019 with maxed out graphic settings on a Nvidia 1070 and I lock the FPS to my refresh rate. This is on a AMD Ryzen 3900X.
Below is my custom edit for my cpu. I suspect there are others that will work, but I've not given it much thought. Once the current bug is out of the beta I'll switch back to pass through and see if that works.

Wanted to come back and give an update now that I'm on 6.9.0 beta 22. There is a bug in qemu on Ryzen 2 CPUs that needs a manual edit to the fix a BSOD and it took me awhile to get the proper edits to my VM config to get it to run, but after doing that I'm not running at a locked 60 fps with no studdering in The Witcher 3.
Win10 thinks my CPU is an EPYC CPU, but it has made things more stable. I'll post what I did if anyone needs this info.
-
@testdasi you are correct. I still have usage on these isolated cores, but I do have less studdering in the games I play. That being said, I've not had much chance to play any games over the last little while.
-
Follow up. Played Fallout 4 most of the night last night, and the skips were mostly gone. Just tested again and it's as smooth as glass on ultra. Even hit my plex server on the same VM with a little transcoding and did not notice anything in game.
I'm not saying it's fixed, and I'd wait till they get a few more betas out before jumping on 6.9.x unraid betas, but for now I'm going to stick on it and hope that there is no major bugs that I get hit with.

You're a brave man
I'm eager to hear your experience on it, hope it fixes it!
hahaa, not normally, but I need this to work as it has replaced my gaming streaming system. So right now with the VM shutdown I have 0s across the board on the CPUs that I have dedicated to the VM. But my unraid is pretty quiet right now, so I'll have to see. I do run PLEX inside the VM as I use the video card to do some transcoding, so I can't leave it offline to watch the cores, but I'll report back. Did game last night and the night before on the beta with a lot less studdering on Fallout 4.

That kind of defeats the purpose... I can't be rebooting my server.
I would expect isolcpus to work as expected.
I feel the same way. Going to test out the 6.9.0 Beta 1 to see if things improve with the new kernel that is in 6.9.x and do some testing. Right now I'm not seeing any load on the issolated cores, but that does not mean much as I just restarted.
-
I'm still getting some activity on HT cores 18 and 19, with the VM powered down as well. When I first applied this and rebooted it seem to be respecting it, but after a few days or running, I noticed higher CPU usage that I was seeing the first few days. Going to reboot and see if I get the same thing.
Update after reboot: CPU usage on these two threads have gone down about 0% with the VM idle. I'll monitor but I expect I will need to reboot the system when whatever process kicks in that is not obeying the exclusions.

What do those two settings do? Any downside?
This is getting a bit technical, but if you want to get more info on these settings, here is NO_HZ. It is around stopping clock tickets for idle CPUs.

And the other. Read Copy Update Ryzen fix...
https://utcc.utoronto.ca/~cks/space/blog/linux/KernelRcuNocbsMeaning
I gamed (streaming using Moonlight) last night for hours, and had a constant 60 FPS with no drops. This is with Fallout 4 (yes it's a little old) and the frame rate is limited to 60, but up to now I was getting some studdering off and on. Not constant, but annoying. I still find the game studders a little when you first start it up, but after a few mins of game play it's gone. I'll test out The Witcher 3 a little over the next few days to see if the studdering is gone in that game as well, but I think this has helped.

Have you tried adding nohz_full and rcu_nocs to your syslinux?
It seems to have worked on my server but I'd like to double check on a different config just to be sure it ain't placebo effects.
I'm going to try this today on my 3900X as I have a fair bit of activity on the isolated cpu cores even with the VMs shutdown. I'll report back if this has had any impact on on my 3900x.
isolcpus=4-12,16-23 nohz_full=4-12,16-23 rcu_nocs=4-12,16-23
Just applied this and rebooted. Cores 6-11 plus the HT 16-23 cores have 0% of usage now with my gaming VM shutdown. Before they would get spikes and hovered around 3 to 5%.
With the VM running but idle, I'm sitting with core 6 at about 3 to 5% and the rest 0-1%. I wonder how much this will affect gaming performance as I was getting a little studdering while gaming.
Thank you for this tip!

I've had this same APU work for transcoding in Windows 10 for PLEX, as I had this setup running PLEX until I swapped it into my unraid box to reduce power usage and consolidate my systems.
So far no luck getting PLEX docker to run with hardware transcoding.
